Teaching a lesson without exposing its source

Once a conclusion is sound, a navy must turn it into courses and training that reach beyond the officers who read the original intelligence. Exercises let crews rehearse the idea under realistic conditions and reveal new problems while the lesson spreads through the service. They can also give a tactic an apparently internal origin by crediting an exercise participant, protecting clandestine or politically sensitive collection methods. Outsiders may suspect that the idea came from elsewhere, but the exercise makes its precise source difficult to prove. The result is a continuing cycle of dissemination, challenge, and revision rather than a single final report.
